SEAL.

Application med August s, 1921` serial 110.490,46.

My invention relates to improvements in seals, and is particularly concerned with the provision of a new seal for securing together the overlapping portions` of metallic strapping used for binding bales, boxes, and packages of all kinds.

The principal objectv of my invention'is to provide a seal which can be'easily and quickly applied to overlapping strapv s ections, afurther object being to provide a seal of the characterV described which can thus be applied to the overlappingl strap 'portions without the necessity of separating them any considerable distance from the package to which the bail is being applied.

A still further object is to provide a seal of the character described which is simple in construction and economical to manufacture.

Other objects will appear as this description progresses, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of my nnproved seal; j

Figure 2 is a plan view thereof, illustrating in full lines the position of t-he seal when it is initially applied to the overlapping strap portions, and in dotted outline the position to which the seal is turned prior to being crimped;

Figure 3 is a transverse section taken on line 3-3 of Figure 2;

j Figure et is a side elevation showing the joint formed after a single crimp has been formed in the seal and' overlapping strap portions; i

Figure 5 is a bottom Vview of lthe joint shown in Figure l, and Y Figure 6 is a plan 4view of the completed joint. i

Throughoutthe several views, similar reference characters will be used for referring' tosimilar parts.

Referring to the drawings my improved seal comprises a more or less rectangular back member 10, the opposite parallel edges 11 of which are provided adjacent opposite endsof the back member with the wing eX- tensions 12 which are bent back over the back member as shown in Figs. 1, 2 and The distance between the adjacent corners 13 o f-the wing extensions is somewhat greater than the Width of the straps to which the seal is to be applied.

In applying my improved seal to a pair of overlapping strap sections 14- and 15, the seal is' positioned relatively to the same asy shown in full lines in Fig. 2, and then turnedi'about anvr axis perpendicular to the back member 10 jto theposition shownin dotted outline in which the extreme ends of the winger:- tensions 12 project beneath'the strap sections'. c 1 z f v'I o vcomplete thefjoint in the strapping, l prefer to crimp the overlapping portions of lthe strap andthe seal as shown in Figs. 4., 5

and i The details of the' crimps formed in thisjomt are clearly illustrated in the pat'- ent' to Flora, 1,252,680, 0f January 8, 1918, i

and further description thereof is thought to be unnecessary.

It will be quite clear that it is a compara#v tively veasy and quick matter to apply my improved seal to the two overlapping ends of the strap, and since the wing extensions 12 are bent over comparatively close to the back member, it isunnecessary to lift the overlapping portions of the strap any considerable distance from the package to apply the seal to the strap. y

While I have described the details of construction of the preferred Iembodiment of my invention. it is to be clearly understood that -my invention is not limited to these details,

- back member opposite each wing terminating in an edge substantially flush with the plane of said back member, whereby the back member can be laid upon said strap portions and theny revolved to swing both end wings under the strap portions.

' 2. A seal for connecting overlapping strap portions comprising a substantially rectangular back member adapted to be deformed, each end of said back member having a single wing folded under the same, said two wings being disposed on opposite sides of said back member and havingr their inner ends spaced apart longitudinally of said back member, the' lateral side of said back Wing folded under the same, said two WingsV being disposed on opposite sides of said back member and having their inner ends spaced sufficiently tar apart to leave a transverse plane area across the wind side of said back member of substantially the Width or' said strap portions, whereby the back member can be laid With said transverse area extending across said strap portions and then revolved to swing both end Wings under the strap .portions 4. In combination, two strap portions, a

, iseal comprising a back member adapted to be deformed, a rst Wing projecting` from said back member and extending under said strap portions, the edge of said back member directly opposite said first Wing normally lying in substantially the same plane as the back member, a second wing proJecting from said back member at the other end thereof and extending under said strap portions, said second Wing being' disposed on the opposite side of said baolr member from said first Wing, the edge of said back member directly opposite said second Wing normally lying in substantially the same plane as the back member, a deformation in said strap portions and said seal in the plane oit said first wing and a second deformation in said strap portions and in said seal in the plane of said second wing. y

5. A seal for connecting overlapping strap portions comprising a back member adapted to be deformed, and a Wing integral with said back member and folded under the same for engaging under the overlapping strap portions, the. portion of said back member directly opposite said Wing terminating 'in a lateral edge lying substantially in the same plane as the plane oi said member.

In Witness whereof, I hereunto subscribe my name this 23rd day of July, 1921.
